IMPROVEMENT IN GAS-BURNERS.

Irire Schedule referred to in these Letters Patent and making part ofthe same.

To all whom it may concern:

specification, whereint igure 1 is a vertical section of the saidgas-burner, an j Figure 2 isa plan ofthe same.

Similar letters denote the same parts.-

Revolving gas-burners have heretofore been made of a'series of metaltubes passing out from a central vertical tube that revolved upon apivot, the jets of gas 'standing' as tangents to the tubular arms, andcausing the revolution of the burner.

Gas-burners of this kind are costly, because the separate parts have tobe united together by joints that are expensive to construct, andy thebiu'ner becomes so heavy as to produce considerable friction upon thepivot, and prevent the burner revolving freely; besides this, the pivotis very liable to wear a hole in the burner, or itself become blunt,thus increasing the friction.

Bearings of stone, and of glass set in metal, have also been used forthe pivot.

My invention consists in formingthe revolving portion of the burner,including the jet-arms, the vertical cylinder, and 'the bearing for thepivot, of one piece in glass, whereby a very light revolving burner isObtained. The pivot-bearing Vis very s1nooth,hard, and frictionless,there are no joints to become leaky, and the holes in the jet-arms donot become corroded'and stopped by the action of the gas and flame', asis the case with metal burners. l

I also attach the baseof the revolving burner to the gas-pipe by arubber tube, so as to prevent injury to the glass, and to facilitate theapplication of the revolving burner to any ordinary gas-burner.

In the drawingsais the vertical tube of the revolving gas-burner; b y

b, the jet-arms; and c, the pivot-bearing; all formed in one piece ofglass.

cl is the vertical supply-tube, with the pivot e at its end, and theside opening i, for the gas to pass out of.

f is the cup to contain mercury, glycerine, petroleuin, water, or otherliquid, in which the lower -end of the tube a revolves, said materialforming a packing to said tube a.

vThe cup f and tube d are united at the point l by cement, such asshellac, to render the parts. perfectly ti ht;

'gThe construction ofthese parts'is facilitated'in consequence of theirbeing made separately, especially whenof glass.

From the lower end of the tube d, an India-rubber tube m extends, so asto be slipped upon the gasburner p, or other tube from which the gas issupplied.

This forms an easy and reliable means of connection, and avoids all riskof injury to the glass in attaching the burner.

What'I claim, and desire to secure by Letters Patent,- is- 1. 'Therevolving gas-burner, with the tube a, arms '-b b, and pivot-'bearing o,all made in one piece of glass,

as and for the purposes specified.

2. The tube d, with the pivot e at its end and' the opening i, incombination with the cup f and .revolving burner, when the cup f andtube d are of glass, andA
